Before they begin calling, all interviewers should receive general training on how to
conduct telephone interviews, as well as specific training on the questionnaire being used for the
study. Refer to “How to Conduct Telephone Interviews” in this section of the manual for an
overview of the general interviewer training new interviewers should receive. The training on the
questionnaire to be used for the study should include an overview of what the major objectives of
the study are, a question-by-question review of the questionnaire, and a review of the Answers to
Potential Questions (APQ) sheet.
